NCP5322A Two−Phase Buck Controller with Integrated Gate Drivers and 5−Bit DAC The NCP5322A is a second−generation, two−phase step down controller which incorporates all control functions required to power high performance processors and high current power supplies. Proprietary multi−phase architecture guarantees balanced load current distribution and reduces overall solution cost in high current applications. Enhanced V2™ control architecture provides the fastest possible transient response, excellent overall regulation, and ease of use. The NCP5322A is a second−generation PWM controller because it optimizes transient response by combining traditional Enhanced V2 with an internal PWM ramp and fast−feedback directly from VCORE to the internal PWM comparator.
